So the water supply has been contaminated and suddenly citizens and CCA alike are becoming ill and dropping to the ground. The plague is contagious through coughing and everyone is paranoid and on edge of strangers and even their friends getting them sick and risking death.
The CCA are too per-occupied trying to mend their now crippled force to patrol the streets effectively.
Doctors need to wear face masks when treating victims of the plague or they will catch it too. CCA need to make a choice between letting people get sick and riot or diverting some of the small manpower it has left to handing out surgical masks to protect against the contagion.
Thoughts? Criticisms? I'm not sure how this would be implemented, so I'm sorta looking to you guys for help.
